Plants and their parts
Part=Structure
Roots
Roots functions
1)They (hold) anchor the plant to the soil.
This is the anchor that keeps the ship in its place
2-They carry water andnutrients to all parts of the plants.
Nutrientssubstances that help living things
grow and stayhealthy .
3) Some plants store foodin them.
Example: carrots
Roots types
1) Taproot
Beet
Radish
Turnip
Carrot
Sweet potato
2)Fibrous root
Cactus
Wheat
Taproot 0r fibrous root?
So, now you can classify the plants according to their root types
Stem
Stem functions
1- It holds the plant up (supports the plant) and enables the leaves to reach sunlight.
2-It carries water, nutrients and food throughout the whole plant.
Water is carried in the stem through special openings called (vessels or tubes)
Stem types
1) Flexible green stem
It is found in small plants Example:Tulip Stem
2) Stiff woody stem(trunk)
It is found in larger plants and trees Example:Tree trunks
Leaves
Leaves have different sizes and shapes
Leaves functions
1)It is the major part in the plant where it makes its own food.
2)It contains chlorophyll (chloroplast) that: a)Gives the plant its green colour.
b)Helps the plant absorb sunlight.
Photosynthesis
Photo = light
People take in O2 and give out CO2
Plants use carbon dioxide to make their food
(photosynthesis) CO2+water+ sunlight food(sugar)+oxygen nutrient chlorophyll
Plant takes in:1- Water and nutrient from the soil.
2-Sunlight soaks the leaves which get energy from the sunlight and trap it in the chlorophyll(chloroplast).
3-Carbon dioxide enters small holes in the underside part of the leaves.
Plant gives off:
1- Oxygen which we use to breathe.
2-Sugar which is the plant food, which gives it the energy needed to grow.
2. Sunlight in
Oxygen out1. Carbon dioxide in
3. Water and nutrients in
Food out
Food=sugar(glucose)
Remember
A green plant breathes all the time, day and night.
A green plant photosynthesizes only in the presence of sunlight.
How plants are different?
• They have different shapes and sizes
How are plants alike?
• 1- Have the same parts
• 2-Make their own food
• 3-They all have green parts
• 4- Grow in the ground
• 5- Can’t move like the animals
